Drawing file is invalid

Registered forum members do not see this ad.

Anyone know of some kind of method of recovering an old .dwg file, that for some reason has become invalid? Recover command does not work. Nevermind, I always seem to type first and then remember about those lovely search functions, sorry!

And are you saying the "recover" command did work?

OK, do you go to the Mechanics and say your car doesn't work or do you probably give some indication of what the symptoms of the problem are. Do you get any indications from the Recover command that you can share with us to help find out where it's falling over?

Do you know what version the Drawing was produced with? Here's a clue to finding out the Database version:
1. Open Notepad and change the File extension to all files
2. Find the offending DWG file and open it
3. The first 6 characters will be something like 'AC1021' and the rest will be double dutch... That gives us the AutoCAD Database version (note: this is not the same as the AutoCAD Software version)

Those first 6 characters will help us to determine the version it was last saved in and thus how old it is and what problems we may be facing... Whatever you do though, DON'T save the DWG from in Notepad - then you'll have no chance of ever getting to it again...

When trying to open the drawing, I get the error message 'Drawing File is Invalid'. The Recover command gives the error message 'Unable to recover drawing file'. I saved it as a .txt file, but it looks like early Greek, there is no recognizable text in the first 6 characters. I tried attaching both the .txt file and the .dwg, but they exceed the size limits. The drawing was last saved in 1997, probably in R14 would be my best guess.

Have someone with 2010 try to recover it, post it here if you can. Have someone with Microstation, Intellicad, DoubleCAD try to open it and save.
